My husband and I enjoyed our stay at Gael's studio apartment. It was very clean, quiet and secure. All things you want after a full day of adventuring in Bangkok. It is also within walking distance of all major public transportation, the river and cabs frequently drive right in front of the building as well.
I never met Gael personally, but all of his associates were friendly and helpful. Not many people who work at this building speak English so that can provide a challenge at times.
In short, I highly recommend Gael and this studio.
